Lady Gaga and Justin Timberlake have fallen victim to European internet hackers, who managed to steal their music it and share it illegally over the net.
Two German men have been arrested over the allegations, with prosecutors claiming they made over £8000 from their wrongdoing.
Other musicians including Ke$ha and Kelly Clarkson are also alleged to have been targeted in the scam, which used a Trojan horse virus to break in to their personal computers.
An ‘intimate’ photograph of a female musician was also reported to have been stolen and used to blackmail the unnamed star in to promoting one of the criminals, who is an aspiring DJ.
The hacking caused some artists to bring tour and album dates forwards in order to try to minimise the damage the leaked music could cause.
However, the men have strongly denied the claims, with one releasing a statement through his lawyer saying: “I’m a fan and I just wanted to have cool music. I’m no blackmailer.”
